Question

the apparent change in the position of an object resulting from a change in the angle or position from which it is viewed is called: options: the doppler effect, parallax, spectroscopy, stellar magnitude

Explanation:

Parallax is defined as the apparent change in the position of an object resulting from a change in the angle or position from which it is viewed. The Doppler Effect relates to frequency - shift due to relative motion, spectroscopy is about analyzing spectra, and stellar magnitude is a measure of a star's brightness.

Answer:

B. parallax
